Abstract
Persistence or image memory is a common problem in infrared array detectors. In WIRCam, the wide-field infrared camera at the Canada France Hawaii Telescope, two of the four Hawaii-2RG (H2RG) HgCdTe imaging arrays in its mosaic exhibit strong persistence while the other two do not. The dependence of the persistence on illumination flux and fluence has been investigated and the persistence measured on the timescale of hundreds of milliseconds to several hours. The goal of this work is to eventually provide an empirical model to correct for the persistence in image post-processing.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
